Unclassified ARIN
Summary
Centre for Addiction and Mental Health
research education enterprise
The registrant field carries a job title where most networks put a department or a role mailbox.
What it's used for
- A hospital and mental health research centre's network. 256 addresses in the single IPv4 prefix
192.197.205.0/24, two observed BGP neighbours, and no IPv6 announced.
Notable
- The block is netname
CAMHV4NET, the institution's initials with the address family and the word for network appended. - The registrant reads as the institution followed by a job title.
- The AS handle spells the institution's full name out in hyphens instead of abbreviating it.
- Three addresses were queried for reverse DNS and none returned a name.
- One prefix, one netname, one registrant, and nothing else in the inventory.
Interesting
- Naming the post rather than a role mailbox means the record points at whoever currently holds that chair. It stays accurate as long as someone remembers to update it when the chair changes hands, which is the failure mode a role address exists to avoid.
- A hospital announcing its own AS for a single /24 is buying route independence rather than capacity. Two upstreams for 256 addresses is a network that must stay reachable rather than one that must carry traffic.
- The handle and the netname disagree about how to write the same name: one spells every word, the other reduces it to initials. Both are in the same registry, describing the same organisation.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 443 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
